To perform validation for an arm-type oscillometric TM-2655 device (A&D Company Ltd, Tokyo, Japan) for blood pressure measurement according to the British Hypertension Society protocol.


Eighty-five study participants (33 men and 52 women) were included in the study. Mean age was 52.9+/-15.0 years, systolic blood pressure range was 84-208 mmHg and diastolic blood pressure range was 48-120 mmHg. For each participant, three readings of TM-2655 were compared with sequential auscultatory measurements by two trained independent observers. The observers used a calibrated mercury sphygmomanometer and dual stethoscope. The results were graded according to the British Hypertension Society protocol 1993.


The average difference between mercury sphygmomanometer and TM-2655 readings for systolic blood pressure was -1.0+5.2 mmHg (mean+/-SD) and for diastolic blood pressure -0.9+/-4.7 mmHg. The proportions of values agreeing to within 5, 10 and 15 mmHg were 72.5, 93.7 and 99.6% for systolic blood pressure and 78.8, 96.9 and 100% for diastolic blood pressure between the observers and the device (A/A British Hypertension Society grade).


The TM-2655 device achieved British Hypertension Society grade A/A and therefore can be recommended for blood pressure measurement in an adult population.
